## Verdicts

**Hotelbeds Hotel Booking API.** Free evaluation key on registration, no card and no sales call. 50 requests a day on evaluation, and the 51st returns a 403.

**LetsFG.** Hosted MCP with OAuth 2.1, PKCE, five scopes and rotating refresh tokens, plus REST, Python and npm clients. Tickets are bought by a LetsFG booking agent after the hold, 4 to 11 minutes per the docs, and bookings can pause with questions.

## Before you call either

### Hotelbeds Hotel Booking API

1. Compute `X-Signature` fresh per request from key, secret and the current epoch seconds, in that order
2. Budget the 50 daily evaluation calls; cache hotel content and only call availability for real dates
3. Run CheckRate on a rate before booking when the availability response says it needs rechecking
4. Read a 403 on the test host as the daily quota first, not a bad key
5. Simulate a cancellation before running it

### LetsFG

1. Start on `/v1/sandbox/` with no key; the booking states, questions and timings match production
2. After `book_flight`, poll `get_flight_booking` every 20 to 30 seconds and answer questions before `expires_at_ms`; an unanswered price change fails the booking and releases the hold
3. Honour `retry_after_seconds` on a 429. Over MCP the limit is 10 searches per 10 minutes and 100 a day, and early retries lengthen the pause
4. Fetch results with `get_flight_results` and the `search_id` rather than searching again, which spends allowance
5. Send the same `idempotency_key` when retrying a booking after a timeout
6. Treat a 410 as a retired route and read the replacement path in its body
